This paper systematically deals with the energy dynamics of Neosinocalamus affinisclonal po-pulation , by quoting the theory of Harper's modular structure at the following three levels :the clonal modules .the clonal rametes and the clonal population.It vvas found that the specific energy value of Neosinocalamus affinis clonal populationwould vary depending on the growth season. the stage of growth and development and theage level. The specific energy value increases in winter (November ,December and January...
